Guys, thank you for your answers. I forgot to include that i should send email as php and the problem is that gmail should correctly display when it was received to include that time for hour calculation and display into email content. I have a user selected timezone in the backend, but people are amazing and wonder why the thing will start after email receival The problem is basically: Your session will start at 6:00 AM, but email is displayed as received at 7:00 AM.

Nonsense question, but still... Is there any method to detect gmail client timezone setting? Like mobile app and web gmail client? Not browser or IP or similar, but gmail. Thank you for your answers.
